This invention relates to grounding devices for use with electrical appartus and more particularly to a grounding device for use in conjunction with radio and telephone receiving and sending apparatus.

An important object of the invention is to i provide a device which will'insure at all times a proper grounding contact.

As is well known to' those familiar with the art, an ordinary grounding device even though embedded in the ground is often faulty in its'operation for the reason that the ground about'the same becomes dry so that it is a less efiicient conductor. Accordingly,

I provision of a structure of this character enibodying means for constantly keeping the ground thereaboutin' a moist condition.

A further object of the invention is to pro 2o-duce in a structure of this character an arrangement such that the moisture is introduced to the'ground below the level thereofand accordingly does not cause a muddy place about the rounding implement.

A still urther object of the invention is v to provide an apparatlis of this character whlch may be very readily installed, which may becheaply manufactured, and which will beidurable and eflicient in service. i '30 A still further object of the invention is to provide a device which may be driven into the ground adjacent a buried grounding device andem loyed to furnish moisture to the grounding evice to insure the integrity of A further object of thi'sinvention is to pro- I duce in a structure of-this character an ar rangement whereby the moisture may bepermitted to enter the ground below the surface thereof so that the moisture will not be quickly absorbed, the water outlet in the tube having means by which the seepage of the water from the tube into the ground may be controlled so that a relatively small reser- 4 voir may be used so as to keep the'device functioning and require fillingof the reservoir or container approximately once a week. These and other objects I attain by the construction shown in the accompanying drawing, wherein for the purpose of illusflattening one end of the tube; The upper end I 15 an important object-of the invention is the replenished from time to time.

tration is shown a preferred embodiment of my invention and where1n:

g Figure l is a side elevatlonal view of a grounding device constructed in" accordance. with an embodiment of my invention;

Figure 2 is an enlarged vertical sectional viewtherethrough; a Figure 3 is a section on the line 33 of Figure 1. e

- Referring now more particularly to the drawing, the numeral 10 generally designates a tube, one end of which is provided with a driving point 11 preferably produced by 'paratus may be. applied.

In the use oft/he apparatus, the tube 10 is driven into the ground to an extent placing the opening 17 below-the level of the groun while maintaining the binding post 18 above the surface thereof. This tube may then be filled with water 'by pouring water into the upper end thereof after which the inverted water jar, which has been previously filled, is placed therein. Water will seep from the tube through opening 17 and moisten the ground about the tribe below and adjacent to this opening. As the water seeps from the tube and the lower end of spout 13 is 'exposedwm additional water will enter the tube to replace that passing from the opening. In order to maintain the tube filled with water it is merely necessary that the water jar be The tube 10 may be made of any suitable material having good conducting qualities and since the body of water contained therein will be constantly in contact not only with the ground but likewise with the inner end of said cone-shaped nozzle,

' extended through the wal or head 19 of the bindih post 18 which is of the tube, a perfeet contact to this bindin post is obtained. As the construction emp oyed is obviously capable of a certain range of change and modification without materially departing from the s irit of the invention, I do not limit myseli to such specific structure except as hereinafter claime I claim 1 'In combination, avgrounding device comprising an elongated tubular member havmg a flattened lower end and an open upper a end, said tube also having an opening in the wall thereof intermediate the ends of the tube, a terminal secured to the tube adjacent the upper end thereof, and a drip member loosely mounted on the upper end of the tubular member, said drip member comprising a reservoir, a cone-shaped drip nozzle depending within the upper end of the tubular memher, an enlarged flange secured to the base said flange normall engaging the u per end, of the tubular mem er, and means or securing said flange to said reservoir;

In testimony whereof I hereunto afiix my signature,

EDDIE F. BENNETT.
